FL consists of hepatoblasts, sinusoid endothelial cells and hematopoietic cells. To determine niche cells for fetal liver erythropoiesis, we isolated each FL component by flow cytometry. mRNA analysis suggested that Dlk-1-expressing hepatoblasts primarily expressed EPO and SCF, genes encoding erythropoietic cytokines. EPO protein was detected predominantly in hepatoblasts, as assessed by ELISA and immunohistochemistry, and was not detected in sinusoid endothelial cells and hematopoietic cells. To characterize hepatoblast function in FL, we analyzed Map2k4(-/-) mouse embryos, which lack hepatoblasts, and observed down-regulation of EPO and SCF expression in FL relative to wild-type mice. Our observations demonstrate that hepatoblasts comprise a niche for erythropoiesis through cytokine secretion."xsd:string |
